| - | Tempus is the KVM template name for CentOS 6.5 on the Proxmox cluster. It was created from a bare Minimal install from CentOS 6.5 netinstall, with common packages (e.g. vim) added for convenience. | ||
| - | |||
| - | |||
| - | ====== Added packages ====== | ||
| - | |||
| - | * vim | ||
| - | * htop | ||
| - | * epel-release | ||
| - | * screen | ||
| - | * wget | ||
| - | * bind-utils (dig and friends) | ||
| - | |||
| - | |||
| - | ====== Cloning ====== | ||
| - | |||
| - | Right click VM 102 (tempus.tardis.ed.ac.uk) under gallifrey and select Clone. Use the following settings: | ||
| - | * Target node: Gallifrey (you can migrate it after cloning) | ||
| - | * Mode: Full Clone (linked ties it to the template!) | ||
| - | * Target Storage: local | ||
| - | * Format: QEMU image format (qcow2) | ||
| - | |||
| - | |||
| - | ====== Post-Clone ====== | ||
| - | |||
| - | After cloning the VM, the VM itself needs some changes: | ||
| - | * Add a Bridged VirtIO Network Device in Hardware (no VLAN, no Firewall) | ||
| - | * Adjust memory capacity as needed | ||
| - | * Expand (not reduce) disk space as needed. Reconfiguring LVM is left as an exercise for the reader. | ||
| - | |||
| - | The VM network needs to be reconfigured (its default is DHCP, with adapter as a NAT to the VM host): | ||
| - | * Set static IP | ||
| - | * Change hostname from tempus.tardis.ed.ac.uk to the correct one. | ||
| - | |||
| - | Both of these steps should be done by running system-config-network, | ||
| - | * In Device configuration, | ||
| - | * Ethernet | ||
| - | * Name can be anything | ||
| - | * Device: eth1 | ||
| - | * Static IP: The machine IP address | ||
| - | * Netmask: 255.255.255.192 | ||
| - | * Primary gateway IP: 193.62.81.1 | ||
| - | * Primary DNS Server: 193.62.81.14 | ||
| - | * Secondary DNS Server: 8.8.8.8 (just in case Leela is down) | ||
| - | |||
| - | Then to load the interface on boot: | ||
| - | * Open / | ||
| - | * Change ONBOOT=no to ONBOOT=yes | ||
| - | * Save. | ||
| - | |||
| - | The needed settings under DNS Configuration are here: | ||
| - | * Hostname: Set to machine name with .tardis.ed.ac.uk postfix. | ||
| - | * Primary DNS: 193.62.81.14 | ||
| - | * Secondary DNS: 8.8.8.8 | ||
| - | * Tertiary DNS: 8.8.4.4 | ||
| - | * Search Domain: tardis.ed.ac.uk | ||
| - | |||
| - | The rest of the VM should(tm) be fully functional out of the box, including root SSH. | ||
